IMPROVEMENT IN? wmoow-sAsHEs.

Specification forming part of Letters Patent No. 190,225, dated May1,1877 application filed March 15, 1877.

To all whom it may concern: I

Be it known that I, LAZARE LANDEKER, of the town and county of San LuisObispo, and State of California, have invented Improvements inWindow-Sashes; and I do hereby declare the following to be a full,clear, and exact description thereof, reference being had to theaccompanying drawings.

The object 01' my invention is to provide such a construction ofwindow-sashes that the panes of glass can be secured in place, andremoved and replaced, whenever desired, by any ordinary person, thusavoiding the necessity of employing a glazier to do the work. Myimprovement also enables me to construct window-sashes so that they canbe taken apart and compactly packed for shipping, after the manner knownin commerce as knockdown articles. I can thus pack the woodwork in onepackage, and the glass in an- 0ther,'saving expense not only in the costof shipping, but also reducing the liability of breaking the glass.

The invention consists in the construction and arrangement of parts, aswill be hereinafter fully described.

Referring to the accompanying drawings, Figure 1 is a perspective viewof a windowsash. Fig. 2 is a horizontal section of thesame.

Let A B G D represent the four rails of a window-sash frame, each ofwhich will be referred to in the specification by reference to theletter A.

' In constructing the mullions which separate the panes of glass I makethem in two parts, b 0 one of which parts, b, forms the outside portion,while the other, 0, forms the inside portion. The outside parts of themullion Ijoint together in the usual manner, and secure them permanentlyacross the sashframe. The parts 0, which are secured upon opposite sidesof the window, I make in short sections, each of which is as long as thepanes of glass used, so that when they are fitted and jointed togetherthey can be secured to the fixed or stationary part by means of devices,herein after described. y I make a dovetail groove, ,0, in the meetingfaces of the inper and outer parts of the multhe parts are in place ametallic or other bar, f, (the opposite edges of which are thickened tocorrespond with the grooves in the mullion-strips,) can be run through ahole in the sash-frame, opposite the grooves, and then passed entirelythrough the mullion, thus connecting the two halves firmly together,and, at'the'same time, serving as a strip to separate the edges of theglass panes.

It is evident that when these sectional halves of the mullion on theinside of the sash are removed, the panes of glass can be simply placedin position, after which the sections of the mullions can be arrangedand secured by the double-headed bar f, so as to confine them in place,and, at the same time, complete the finishing of the sash.

Ordinarily, however, I shall make a longitudinal slot, h, in the edge ofthe outside rails AB C D, opposite the grooves in the mullions, throughwhich the panes can be slipped in the manner of a drawer until they areproperly placed. I then place a strip, j, of Wood or other filling ineach slot, and secure it in place by screws or otherwise.

When a pane is to be removed and replaced after the sash has been onceset up, I shall simply remove this filling-strip, and remove and replacethe glass through the slot; but in the original setting up of the frame,before the sectional mullions on the inside of the sash are fitted andsecured in place, I will place the glassdirectly in position, andafterward secure them by fitting and securing the sections.

Either of the abovedescribed devices can be used independent of theother for removing or replacing the glass panes in the spaces, and whenthe sash is not intended to be knocked down I shall only use the slotsin the edges of the side rails of the frames; but when the sash isintended to knock down [shall probably use both devices, although theslot in the edge could be dispensed with.

Various methods of constructing a sectional mullion could be devised foraccomplishing the abovementioned objects; but the one I have representedis cheap, simple, and quite efi'ective.

By taking the mullions apart and knocking lion, and opposite each other,so that when out the pins which fasten the corners of the sash-frame, Ican pack all the parts in a very small compass for transportation, andship the glass panes in a separate package. Any person of ordinary skillcan then put the parts together, insert the panes of glass, and completethe window. If the panes of glass should rattle, a very small quantityof putty inserted in the groove will render them tight.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

The combination, with the side rails of the frame A B O D, provided witha slot 01' slots, h, of the dovetailed grooved mullions b c anddouble-headed bars f, substantially as and for the purpose specified. y

In witness whereof I have hereunto set my hand and seal.

LAZARE LANDEKER.
